We used the Sharpie Fine Point Permanent Markers for my daughter's birthday party. The friends made their own pillow cases uses the markers. They would create their own design and then spread isopropyl on the pillow cases. After drying overnight, we put the pillow cases in the dryer and that made the creations permanent. We always use Sharpies because of the high quality of the product. I honesty don't even know of another permanent marker that I could use if I wanted to do so. Sharpies are the best.

I have used these in some many more ways than I'd planned to. I'm very glad I splurged and bought all these colors. It has come in very handy to have the color choices in a marker that writes on almost anything.
